Remove these directories:
/Applications/Xamarin Studio.app /Developer/MonoTouch /Developer/MonoAndroid /Library/Frameworks/Mono.framework /Library/Frameworks/Xamarin.Mac.framework /Library/Frameworks/Xamarin.Android.framework
Locations in your user directory:
~/Library/Caches/Xamarin ~/Library/Caches/XamarinStudio-4.0 ~/Library/Developer/Xamarin ~/Library/Developer/XamarinStudio ~/Library/Logs/Xamarin ~/Library/Logs/XamarinStudio-4.0 ~/Library/Preferences/Xamarin ~/Library/Preferences/XamarinStudio-4.0 ~/Library/Xamarin ~/Library/Xamarin.Mac ~/Library/MonoTouch ~/Library/MonoAndroid ~/Library/XamarinStudio-4.0
That’s all there is afaik.
